Application filed July 19, 1922. Serial No. 576,097.

To all whom it may concern Be it known that I. FmNgoIs PAUL, a British subject. residing at 9 Laval Avenue, in the city of Montreal, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in Sanitary Apparatus for VVater- Closets; and I do hereby declare that the following is a true, clear, and exact description of the same.

The present invention relates to improvements in a sanitary apparatus for water closets, which is fully described in the jollowing description. and accompanying drawings:

Referring to the drawings, Figure 1 is a side elevation of the apparatus.

Figure 2 is a front elevation of a portion of the apparatus.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is a water closet bowl, and 2 isthe usual water tank. 3 is the ventilation pipe which communicates with the room. The ventilation pipe I 3 usually projects through the ceiling 4:, as

disclosed in Figures 1 and 3. Suitably connected to said pipe 3 is a curved extension pipe 5, which has a slanted open end 6, said open end 6 being closed by the pivoted valve 7 Rigidly secured to-said valve 7 extends in opposite direction the lever 8. Over the bowl 1 is provided the usual seat 9 and cover 10. The seat 9 is provided with a strip 11 therearound, in order to elevate it, so as to allow suflicient space to secure the suction chamber 12. This suction chamber 12 is disclosed in the drawings as fitting in the rear of the seat, but without departing from the spirit of the invention, it may be secured in any convenient place below the seat, or the bowl may be specially constructed to provide for same. From said suction chamber 12 extends the pipe 13. which communicates intermediate of said curved extension pipe 5. On the water tank 2, or in any other suitable place, is pivotally secured at 14: the lever 15, said lever being provided at one end with a weight 16, the other end of said lever being connected to the lever 8 on the valve 7 by means or a cord of wire 17. On one side of the seat 9 is rigidly secured a lug 18, which extends below said lever 15, and 19 is a spring provided in the forward end of the seat 9, and adapted to slightly raise the seat 9.

In the operation of the invention above disclosed it will readily be understood that the weight of the body will naturally compress the spring 19 and cause the lug 18 to contact with the lever 15. thereby slightly tilting it, as disclosed in the dotted line in Figure 2 of the drawings. By so doing, the lever 8 will be pulled down. hermetically closing the valve 7. The result will be that a natural suction will take place in the bowl, drawing all odors on account of the tempera ture in the bowl being relatively higher than the temperature at the end of the ventilation pipe. This will be easily understood as being due to the emanation of bodily heat into the bowl. The hot air in the bowl being lighter than the cold air at the end of the ventilation pipe 3, a natural suction will take place. The suction will naturally be lessened to a certain extent when the body weight is removed from the seat. When the body is removed from the seat, the seat 9 will resume its normal position, thereby opening the valve 7. The object of opening the valve 7 when the body weight is removed is to allow the ordinary ventilation of the room. Evidently, the room willbe ventilated through the open end 6 of the extension pipe 5. as well as through the suction chamber 12.

It should be understood that only one form of the invention has been described and disclosed in the accompanying drawings, and that any modification can be made, so long as it does not depart from the spirit of the invention and the scope of the accompanying claims.

The main object of the invention is to eliminate all odors emanating from the bowl. To attain this object the odors must be sucked from the bowl and not allowed to permeate the outside air, which happens with the usual type of ventilation.

What I claim as my invention is:

1. A device of the character described in combination with a water closet bowl and the ventilation pipe, a pipe leading from said bowl to the ventilation pipe, said ventilation pipe having an opening therein leading into a room; a valve adapted to close said opening; and means including a weighted lever actuated by the movement of the water closet seat to actuate said valve, substantially as described.

2. A device of the character described in combination with a water closet bowl and a ventilation pipe consisting of a pipe leading fIiOIILSfiid-bOWLtO said ventilation pipe; an openin r in said pipe leading intothe room; a vzfive adapted to close said opening; and means to close said valve simultaneously with the pressure of the body on the seat of the bowl, snbstantiallyes described.
